When you get to the point you have a ton of groups to keep track of, buy a cheap car with a good surface area, like a MINI... Put a single white or light color decal square on the side, and stretch it to cover the whole side. Copy/paste it to all the other sides of the car.
Now you can load that tire group on the side, the oil group on top, another on the other side as well as the front/back...
Then save the the whole thing as a design for the car. You can organize them any way you want, I tend to put major sponsors, car companies, fuel/oil related etc on different cars and then name the design applicably.
That way as you accumulate different types of decal groups, you can take them out of your decal section so you don't have to scroll through 120 decal groups.
When you need a specific set, you load the MINI. Hit the start/triangular button to "load for this type of car only" so that only the MINI designs show up in the list.
Then load the design. Go into the decal application facility, go to the side of the car you want, high-lite the group and then "save group as". You now have that group at the front of the line in your decal groups list.
When you exit, DON'T save the changes to the MINI. That way it will be the exact same way next time you need something else on that car. Not saving changes is important, never save them unless you purposely changed something you wanted to on the design, like adding a new sponsor. Then you want to re-save the design anyway...
Now just go back and grab your project, load the layer group just like you do now and do whatever. When you're done, delete it if you know you won't need again anytime soon. No need to worry, it's still on the MINI as part of the design file...
You may think it's a little bit of a chore to do this, but when you have 70+ MINI's full of decal groups (and 15 little Fords) on hand, it's the easiest way to keep them close at hand, but not in your way... ?B)
